This is a solution designed for the SME market. (We reviewed version 6, but 6.5 is now available.) Instead of simply making incremental backups Retrospect Backup uses backup sets to ensure all data can be recovered. Whereas many solutions only copy the new or changed part of a file, Retrospect keeps a set of all changed data so that if you later find that the version you have been working on has errors in it you can call back the 'best' version. Saved to your hard drive as well as to the server, a user can quickly call up and restore the version that they need to refer back to.
